FIELD: metallurgy.
SUBSTANCE: invention relates to foundry field. Device contains chamber, fixed outside to the surface of mold or moulding box. Chamber is implemented in the form of plate and, sidewise of its fixation to mold at joint on the periphery it is outfitted by compactor for pressure-tight joint and allows holes and/or grooves or free space for gases passing. Plate fixation to the mold surface or moulding box is implemented by means of vacuum in a plate.
EFFECT: it is achieved effectiveness increase of molds vacuum compaction.
